Active region magnetograms for solar flare prediction: Reduced resolution dataset

In this dataset, we provide a comprehensive collection of magnetograms
from the National Aeronautics and Space Administration's
(NASA's) Solar Dynamics Observatory (SDO).  The dataset
incorporates data from three sources and provides SDO Helioseismic and
Magnetic Imager (HMI) magnetograms of solar active regions as well as
labels of corresponding flaring activity.  This dataset will be
useful for image analysis or solar physics research related to magnetic
structure, its evolution over time, and its relation to solar
flares.  The dataset will be of interest to those researchers
investigating automated solar flare prediction methods, including
supervised and unsupervised machine learning (classical and deep), binary
and multi-class classification, and regression.  This dataset is
a minimally processed, user configurable dataset of consistently sized
images of solar active regions that can serve as a benchmark dataset for
solar flare prediction research.  This dataset consists of
reduced resolution images (see usage notes below).
